    Ami (owner) and his team are great! We needed help finishing a lead abatement process on our patio…read morethat we began ourselves and then realized was bigger than we could handle - specifically in TWO WEEKS before our sons 1st Birthday Party. Ami was honest, respectful, and gave us multiple options on how to proceed to keep our budget in mind. His team went above and beyond covering areas that we originally didn't anticipate, and focused on making sure first and foremost the area was safe for our toddler to play under. We'd highly recommend Ami & Haztek to anyone needing Lead Abatement work!

    After the Palisades fire, I hired Haztek to address light smoke and asbestos dust in two areas of…read moremy home. The owner, Ami, presented himself as highly experienced with wildfire remediation and repeatedly warned me that other companies--and even my insurance--would not protect my family. I have two very young children, and I relied on what he told me. Only later did I realize that most online reviews were from people who had phone consultations, not verified wildfire remediation customers. During the project, Ami also told me he was receiving many referrals from my then-State Farm adjuster after I introduced them. Without my knowledge, he brought a public adjuster to my home and was seen on my doorbell camera discussing all the work he received since that introduction. I never consented to my home being used in this way. Haztek initially sent my insurance an estimate over $160,000. After they learned my policy limit was $100,000, the estimate dropped to $84,000, and I was asked for a 50% deposit. I later learned this deposit structure is not allowed for this type of work in California. After work began, contamination increased dramatically. - Initial asbestos levels around 1,000 structures/cm² rose to over 100,000 structures/cm² in the same areas. - Lead levels that were originally within safe EPA limits (one area at 3 µg/ft²) increased to as high as 69 µg/ft² after a chimney sweep. Visible ash remained around the fireplace, in a room labeled as a clean area for furniture. When I asked about the visible ash and the results, I did not receive clear explanations. We failed two clearance tests over two months, each showing higher contamination. While this was happening, extensive demolition occurred, without permits or testing for lead/asbestos despite our home being built in 1974. This included drywall, hardwood floors, cabinetry, tile, and bathroom fixtures. I only discovered it when my doorbell camera showed my toilet sitting on my doorstep causing me to drive home and find total destruction. When I asked why I hadn't been notified, the explanation I received didn't match the dates shown on camera. I was told demolition was due to mold. Two licensed mold companies later performed moisture testing and confirmed there was no moisture problem. The demolition caused major damage to my home. I also have footage of appliances being moved in ways that damaged surrounding floors * Dust/Ash remained on multiple surfaces after work was marked complete. * When I asked what justified their costs being so much higher than companies like Servpro, no specific differences were provided. * PPE usage was inconsistent. When I was present, it was used; camera footage on other days I wasn't showed workers didn't. * Several items labeled "keep" went missing, including irreplaceable baby keepsakes. Smart devices they claimed were non-cleanable later appeared active and used at a different location, with streaming accounts still logged into and used. * Reported work hours didn't match what was captured on camera. Haztek demolished our HVAC closet, which contained popcorn material. No containment was used. I have photos of this material falling into the HVAC system and return ducts. Afterward, asbestos levels in nearby areas tested extremely high. This demolition was not part of the original wildfire or asbestos dust scope. By the time I understood what was happening, our insurance benefits were nearly exhausted, and our home was left with higher contamination and heavy damage. We ultimately discarded nearly all belongings. The impact on our family has been significant. Haztek advertises expertise in asbestos, lead, fire, and mold remediation. When I checked the CSLB website, the listed license showed a general contractor license. I was not able to locate: * A C-22 asbestos abatement license * CDPH lead abatement certification * IICRC fire or mold remediation certification If you are dealing with wildfire or hazardous cleanup, I strongly recommend verifying all licenses with the appropriate agencies, using independent third-party testing, avoiding large upfront deposits, and confirming all scope details in writing. I hope sharing my experience helps someone else avoid what we went through.

    After my plumber discovered extensive sewage leakage beneath my house, we needed immediate cleanup…read morebefore any repair work could begin. We contacted Scope Environmental because they specialize in a wide range of services, including sewage and mold remediation. Veronika was courteous, highly responsive, and scheduled a team to come out the same day. Peter and his crew were professional, efficient, and thorough. They quickly extracted the standing water, debris, and sewage, then applied absorbent materials to the wet areas to remove moisture. They also installed heaters and drying equipment to prevent further damage. I appreciated that they returned over the following days to monitor progress and ensure everything was drying properly. Their support during such a stressful situation made a world of difference. I highly recommend this reliable, family-owned company for anyone needing this kind of emergency cleanup services.

    "Multiple Layers" of Deception and Unprofessionalism…read more.. In my correspondence with Gene K., a representative of Scope Environmental (cut and pasted from Yelp chat room) mentions "We can definitely help. Our asbestos inspection, survey, and lab results pricing is very competitive. It's $625 for the inspection and report. Each sample is $35. No other fees. Generally, results and reports will be available within 24-48 hours". Gene K. also mentioned the following "Some samples have multiple layers, and that can not be determined prior to taking the physical sample. You are welcome to call in so that you can properly comprehend the procedures". However, UNDISCLOSED FEES can creep into the price charged to the customer, e.g. such as the need to test "multiple layers" of one material; so, "No other fees" is (deliberately) misleading and therefore, deceptive. A field inspector (Daisy Flamenco) of Scope Environmental, arrived at the project site and upon seeing the area that needed sampling, asked the homeowner for a ladder to get her modest stature to the sampling material areas. When sampling the ceiling, Ms. Flamenco was barely able to reach the sampling surface (needed to be on her tippy toes), even with a step ladder (provided by the homeowner). ALL sample takers must come fully prepared for all conditions at the work site and not rely on the homeowner to provide tools, equipment or assistance of any kind to do THEIR job! Ms. Flamenco was dressed casually, no respirator or other appropriate protective equipment or gear, which is not only hazardous to herself, but sends the message to the homeowner (overseeing the work), that asbestos is really not that harmful. Even two and a half years following the end of the COVID-19 pandemic, it is appropriate if all workers who enter a home, to wear a mask or at least offer to wear one, but Ms. Flamenco failed to show the occupants of the residence, such consideration. Most (professional) people return to bad pre-pandemic habits, even if to protect the home's occupants from the common cold. What is really inconsiderate and unprofessional, is that Ms. Flamenco had disturbed suspected asbestos containing materials by scraping and cutting away material from parts of a furnace and its ducts, leaving the furnace and ducts out-of-order, i.e. if no asbestos or other harmful materials were found, the furnace and ducts could not be safely and effectively used without first repairing them. Leaving carcinogenic materials exposed (cutting, scraping or otherwise removing and exposing asbestos) to those who live at the work site, is hazardous and unprofessional and should never be done this way. Exposing harmful materials puts people and animals at risk of exposure to carcinogens and asbestosis causing particles! Asbestos sample takers should take measures to seal or otherwise cover, exposed asbestos containing materials (when they are through sampling them), to protect home occupants. This experience was a wake-up call to how incompetent workers can make a bad situation, worse!

    I cannot say enough good things about Restoration Masters and the way they handled our home after…read morewe experienced smoke and debris damage. From the beginning, they were professional, knowledgeable, responsive, and extremely thorough. What impressed me most was that they truly advocated for doing the job correctly. When the initial insurance scope did not fully address everything that needed to be restored, Restoration Masters took the time to document the damage, explain why additional work was necessary, and provide the information needed to support the supplemental work. They weren't interested in taking shortcuts--they wanted to make sure our home was properly restored and safe for our family. Gary was especially wonderful to work with. He was patient with all of our questions, kept us informed throughout the process, and helped us navigate a stressful insurance claim when we weren't always sure what the next step should be. Having someone knowledgeable on our side made a huge difference.

Not only did they do an incredible and fast job, they surpassed expectation at every turn. They kept telling me, "we'll have to check our schedule, we're very busy, it might be awhile" and yet here I am 2 weeks later with the job done. They also came in quite a bit under another quote. It was a great experience and I won't hesitate to call them again if the need arises.
